UPDATE: POLICE are investigating a serious four vehicle traffic crash that occurred in Gootchie earlier yesterday.
Investigations suggest around 10.30am, a sedan was travelling southbound along the Bruce Highway, 20km south of Tiaro before it crossed to the other side of the road before hitting a second sedan.
As a result of the collision, the second sedan collided with a guard rail and then ricocheted to the opposite side of the road before colliding with the rear of a trailer being towed by a truck and then head-on into a third sedan.
The 48-year-old male driver of the second sedan was taken to Gympie Hospital in a serious condition while the 45-year-old female passenger was flown to the Royal Brisbane and Women's Hospital in a critical condition.
A 16-year-old female passenger of the third sedan was flown to Nambour Hospital in a serious condition while a 17-year-old female passenger was transported to Gympie Hospital with minor injuries.
The Bruce Highway at the incident location was closed for approximately four and a half hours.
Investigations into the crash are continuing.
YESTERDAY: Two people have been airlifted to hospital after a four-car crash at Gootchie, south of Tiaro, with one woman in a critical condition.
The RACQ Careflight and EMQ rescue helicopters flew to the scene of the crash, which happened about 10.30am on Saturday.
RACQ Careflight's medical team treated a middle-aged woman who had suffered critical injuries.
The flight doctor and flight intensive care paramedics worked to stabilise the woman before airlifting her to the Royal Brisbane and Women's Hospital in a critical condition.
Speaking at the scene, Sergeant Steve Webb from the Wide Bay Forensic Crash Unit said investigators already had a clear idea of how the crash had unfolded.
"The initial inquiries show that a black sedan that was travelling southbound has drifted on the incorrect side of the road and collided with a blue sedan that was travelling northbound.
"That sedan in turn has collided with another southbound sedan and somewhere in the mix someone has hit a semi-trailer and caused relatively minor damage to that vehicle."
Sgt Webb said several people involved in the crash had sustained serious injuries.
"Well at this stage the people in the blue car behind me have been taken to hospital. The passenger is in a critical condition. The other is in a serious condition and another young woman is in a serious condition as well.
When asked if those involved in the crash were lucky to have escaped with their lives, Sgt Webb replied "well yes - at this stage".
"One's been flown to Brisbane," he said.
"It could have been a lot worse."
Sgt Webb said he made no apologies for closing the highway for a few hours to deal with the aftermath of the crash.
"We've got to gather our evidence," he said.
"Unfortunately that's the nature of driving on the road nowadays.
"If something like this happens, you'll have to wait, I make no apologies for it."
Sgt Webb said he could preach road safety until he was blue in the face.
"I mean, what have I got to say?" he said.
"This is the second serious crash I've been to in a week.
"We send out the same message all the time.
"You know, these tragedies are avoidable."
The highway remains closed in both directions.
EARLIER YESTERDAY: A serious four-vehicle traffic crash at Gootchie has closed the Bruce Hwy in both directions.
The crash happened on the Oaky Creek Bridge, near the intersection of Deveron Rd , about 15km south of Tiaro.
The highway will be closed for several hours and motorists are being advised to seek alternative routes.
